Supply line 6 also comprises a brake equipment of describing in detail 43 in Fig. 2, this device comprises a stepping motor 44 again, by the operation of coder 12 and sensor 45 control step motors 44.Described sensor 45 is positioned at the upstream that nestles up cylinder 10 in the face of the last branch line 16 of load-transfer device 8.Described stepping motor 44 can make has a cylindrical head 46 of etcetera 47 rotate (among Fig. 2 along conter clockwise) radially.The free end of etcetera 47 separates certain distance with the rotating shaft of cylindrical head 46, and this is apart from the distance between the last branch line 16 that equals described rotating shaft and load-transfer device 8 at least.The free end of described etcetera 47 with 8 identical speed at least along the part operation of its running route, and engage with last branch line 16 with given contact pressure in each commentaries on classics of cylindrical head 46.
At last, supply line 6 comprises a control setup 48, this control setup 48 comprises a central controller 49 again, when central controller 49 from load cell 15 with the detector 51 that is used for determining the angle position of oblique arm 24 when receiving signal, these central controller 49 controls provide the operation and the conveying of the fluid pump 50 of actuating fluid to actuator 26.
The operational process of wrapping machine 1 is described below, and this moment, bearing pin 27 did not load, and electrical motor 13,38,42 and 44 is not switched on.
According to situation recited above, full material volume 29 is placed near wrapping machine 1; Make actuator 26 drive oblique arms 24 and clockwise rotate (Fig. 1), thus bearing pin 27 leave conveyer 7 with 8 last branch line 16, this distance of leaving is rolled up 29 diameter greater than material; Bearing pin 27 is in extracts the position out, and the material volume 29 that is installed on the bearing pin 27 is shown in an open position; Central controller 49 driven fluid pump 50 make oblique arm 24 rotate counterclockwise around bearing pin 25, make the periphery of expecting volume 29 be positioned at the top of the last branch line 16 of load-transfer device 8 thus; To there be support belt 30 material base 2, that have given initial length to launch from material volume 29, and along last branch line 16, below the brake equipment 43 by the passage that manually passes between cylinder 10 and running roller 18, pass the passage between the running roller 34 of running roller 18 and spacing changeable device 35, and the passage between the running roller 39 of running roller 37 and assembly 36.
At this moment, make fluid pump 50 work again,, fall within on the branch line 16, thus, will be applied to successively by the tensile force that load cell 15 is measured on branch line 16 and the axle 14 with the circumferential seat that causes material volume 29 so that material volume 29 further descends.When tensile force reached given value, central controller 49 made fluid pump 50 out of service, and and for example this controls keeping branch line 16 to have given tensile force subsequently for it, and driving motor 13,38 and 44.
When driving motor 13 and 38 operations, last branch line 16 is carried out with given constant speed towards direction 3 and is supplied with motion, and support belt 30 launches from material volume 29 with same speed.When material volume 29 was in basic full state, electrical motor 38 can not launch support belt 30 individually, therefore need be by device 41 driving motors 42.
In case the empty material circle of several circles is eliminated, support belt 30 just begins to supply with along the last branch line 16 of load-transfer device 8 the continuous string 31 of overlapping material base 2, so that material base 2 moves below brake equipment 43 continuously.When contacting when fwd material base 2 arrival devices 35 and with running roller 18, the etcetera 47 of brake equipment 43 just contacts each material base 2 at the trailing edge of previous material base 2.The size of etcetera 47 will make and will be pressed in by the material base 2 of its joint on the last branch line 16 of load-transfer device 8, thereby prevent at synchronization, take out two or more material bases 2 by running roller 18, and the continuous string 31a of material base 2 can be supplied with running roller 19 and wheel 4, wherein, with overlapping opposite, between described material base 2, form uniform spacing, this spacing equals the width of the material base 2 measured along service direction 3 at least.During etcetera 47 and material base 2 move contiguously, by the rotating speed of coder 12 control etcetera 47, and during both noncontacts, by the rotating speed of sensor 45 control etcetera 47; Passing through of the trailing edge of sensor 45 each material base 2 of detection, and control motor 44 like this make etcetera 47 contact each material base 2 near the downstream of the trailing edge of previous material base 2.
Therefore, compare with continuous string 31a, material base 2 in the string 31 has quite little spacing continuously, like this, for the material base 2 of giving determined number of in unit time to wheel 4 supplies, the moving velocity of the material base 2 in continuous string 31 is littler much than the material base among the continuous string 31a, for example, in the present embodiment, the former is approximately the latter's 2/3rds.Because their overlapping setting and have relatively slow moving velocity, therefore the material base 2 in the string 31 does not need holding device or guide piece continuously.
As shown in Figure 1, supply line 6 comprises a material volume switching device 52, this material volume switching device 52 is between oblique arm 24 and brake equipment 43, above branch line 16 on the load-transfer device 8, it comprises that successively one is positioned at the arm 53 of branch line 16 tops, this arm 53 is positioned at the side of branch line 16, and is relative with oblique arm 24.One end of hold-down arm 53 connects support 23 by a bearing pin 54 that is parallel to bearing pin 25, and rotates around bearing pin 54 under the control of angle position detector 55 and line style actuator 56.Described line style actuator 56 is arranged between the mid point of support 23 and hold-down arm 53, and uses the fluid pump 57 supply pressure fluids by central controller 49 controls.The free end of hold-down arm 53 is equipped with bearing pin 58 in rotating mode, and this bearing pin 58 is parallel to bearing pin 54, and stretches out from hold-down arm 53 directly over last branch line 16.
By a known actuator (not shown) bearing pin 58 is moved vertically with respect to hold-down arm 53, so that engage an end of centre hole (not shown) by mandrel 28, described mandrel is with in use relative by the end of bearing pin 27 joints, and, as shown in Figure 1, usually by hold-down arm 53 bearing pin 58 is remained on the spare space, this spare space is positioned on the circular trace 59 of the bearing pin 27 of bearing pin 25 rotations.
Device 52 also comprises a known lapping device 60, and it is provided with in the face of last branch line 16, between hold-down arm 53 and brake equipment 43; And a known cutter sweep 61, it is between hold-down arm 53 and last branch line 16.
In actual use, when launching support belt 30, keep its last branch line 16 contacted material to roll up 29 diameter by actuator 26 and reduce gradually, so that oblique arm 24 makes bearing pin 27 move along circular trace 59 gradually along conter clockwise (Fig. 1) rotation with load-transfer device 8.This action is carried out continuously, and is coaxial with bearing pin 58 up to detector 51 indication bearing pins 27, and discharges bearing pin 27 simultaneously and drive bearing pin 58, bearing pin 58 is inserted in the mandrel 28, extracting mandrel 27 out, and draw back oblique arm 24, keep material volume 29 to link to each other with hold-down arm 53 by bearing pin 58 from material volume 29.
At this moment, oblique arm 24 unloadings are returned, and receive new material volume 29, and simultaneously old material volume continues to launch on bearing pin 58; Make oblique arm 24 enter ready position; There is not the part of the support belt 30 of material base 2 to be applied to the upstream end that just is positioned at the material volume 29 that is launching along last branch line 16.
When also remaining only several circles do not have the support belt 30 of material base 2 on detecting mandrel 28, detector 55 drives gettering container 17 and cutter sweep 61, make the support belt 30 and the last branch line 16 of virgin material volume 29 form one each other by gettering container 17, and the end section of the support belt 30 of the material volume 29 that has launched by cutter sweep 61 cutting, and it is placed on the fore-end top of support belt 30 of virgin material volume.Because the effect of gettering container 17, advance to assembly 36 with identical speed in the end of two stacked support belts 30, and by device 60 overlap joints.
At this moment, the material of matting volume 29 unloads from bearing pin 58, begins to launch virgin material volume 29 simultaneously.
